Everything About Car Exhaust Gasket
Gaskets for exhaust manifolds are often made of embossed steel in several layers. High-temperature fibre material, graphite, and ceramic composites, among other materials, make these gaskets. Some gaskets are made up of many materials. Flange gaskets and ring gaskets found at different link points in the exhaust system are examples of different types of exhaust gaskets. The materials used to make these gaskets are typically the same as those used to make exhaust manifold gaskets.

What Is A Car Exhaust Gasket?
A gasket is a mechanical seal that helps to fill the space between two surfaces. It helps to prevent leakage or seepage, both into and out of the joint between the two surfaces. For instance, where both solid metal surfaces meet like a joint in a pipe. If the seal is not perfect, it can create a gap which can cause the liquid or gas to enter or escape from the joint. A gasket helps to fill this gap.
What Are The Types Of Car Exhaust Gasket?
There are three main types of gaskets present in this system:
- Exhaust Manifold Gasket
- Exhaust Flange Gasket
- Header Gasket
Exhaust Manifold Gasket
- The exhaust manifold gasket is found between the engine head and the exhaust manifold.
- This gasket is produced in such a way to withstand the extreme pressures from the cylinders and high temperatures from the gases which travel through it.
- This type of gasket is made of metal, typically steel, on the manifold side and the engine head side is made of a fibre material so that the manifold has a moving room against the metal part of the gasket.
Exhaust Flange Gasket
- Donuts gasket, which is also the other name for the exhaust flange gasket is found between the catalytic converter and the header pipe.
- Exhaust flange gasket helps to improve the flow of the gases through the vehicle’s exhaust system and is equivalent to the manifold gasket, which means it is also typically made of steel and can withstand high temperatures.
- The joints of this gasket are made from materials such as rubber, graphite or ceramic fibre.
Header Gasket
- Header gaskets are found between the cylinders of individual exhaust pipes, manifolds, and the collector pipe; these gaskets help in sealing the gaps so the exhaust gases can flow through those areas with no leakage and will eventually exit through the tailpipe.
- Header gaskets are made of high-fibre materials along with a steel filler to withstand the heat and pressure-resistance.
- The purpose of these joints is to get the gases from the engine through the vehicle’s exhaust system into the atmosphere and fits the specific needs of each part.
What Materials Are Used For Making Car Exhaust Gasket?
Exhaust gasket is typically made up of – SPAF II, Tang Graphite, Novus Ti, non-asbestos fiber (many variations) and Nitrile Cork.
What Are The Important Features Of Car Exhaust Gasket?
The important features of the exhaust gasket are:
- It is made from high-temperature materials.
- It is made up of a combination of metal and graphite to increase sealing efficiencies.
What Are The Symptoms Of Bad Exhaust Gasket?
Engine exhaust manifolds are the metal components which hold responsibility for collecting exhaust gases and sending them to the exhaust for discharge from the tailpipe. They are fixed tightly to the engine cylinder head(s) and are sealed with the help of a gasket known as the exhaust manifold gasket.
The exhaust manifold gasket is a multi-layered gasket which has the metal and other materials that are made to provide the best deal possible. The exhaust manifold gasket is a very important seal, as it is the first in the vehicle’s exhaust system, and should be properly checked if any problems arise. If it is faulty or has any issues, it can cause many troubles for the vehicle. A bad or failing exhaust manifold gasket will show a few symptoms where the driver can alert of the potential issue.
Excessively Noisy Engine
- The very first symptom of a problem with an exhaust manifold gasket will be the excessive noise from the engine.
- If the exhaust manifold gasket is faulty, then it will produce an exhaust leak with hissing or tapping sound coming from the engine.
- You will hear this sound, especially during a cold start or during acceleration.
Decrease In Power, Acceleration, And Fuel Efficiency
- Performance issues in the engine are another common symptom of a problem with an exhaust manifold gasket.
- Faulty exhaust manifold gaskets can cause exhaust gasket leakage resulting in engine performance issues like decreases in power, acceleration, and fuel efficiency.
- The performance decrease might appear to be a minor problem at first, but later it will worsen over time if not addressed promptly.
Burning Smell Coming From The Engine Bay
- Burning smell from the engine bay is another symptom of a potential problem with the exhaust manifold gasket.
- If the gasket fails and starts leaking near any plastic components or engine wiring, then the components may burn up because of the heat from the exhaust gases.
- This will produce a burning smell in the engine bay as the components were exposed to high heat. Faint smoke may accompany the smell.
- If there is any burning smell it should be checked as soon as possible to ensure that they are not a potential safety hazard.

What Are The Steps Of Changing My Car Exhaust Gasket?
Here are a few steps how you should change the exhaust gasket.
Step 1: Let Engine Cool Off
If you have been driving, allow your engine to cool down. You have to wait for approximately an hour.
Step 2: Remove Manifold Bolts
Spray some penetrating oil in the manifold bolts. As they are subjected to high heat, they will eventually weld themselves to the manifold. The sprayed oil will help you to break the bond with your wrench. With the help of a socket wrench, and with an extension if you need, take off the bolts. Make sure not to break the bolts when you remove.
Step 3: Scrape Old Gasket Off
The old gasket will be sealed onto the metal parts of the manifold and the cover. With the help of a small putty knife, scrape off the old gasket. Get rid of it as it will cause the manifold to leak.
Step 4: Set New Gasket
Now fix the new gasket in place on the manifold and change the cover. With the new bolts, tighten the manifold cover down. A torque wrench will keep you from over tightening the bolts which might cause it to warp or crack.
